 If your vehicle experiences idling vibrations or weak acceleration while driving, it may be due to a problem with the fuel injectors. Replacing the fuel injectors may require resetting them using a diagnostic tool. This article will introduce how to use the LAUNCH X431 diagnostic tool to perform fuel injector matching on a 2024 FIAT Pulse. Background Description : The function of vehicle fuel injectors is to atomize fuel, thereby improving combustion efficiency and reducing carbon buildup. Modern fuel injectors use ECU signals to control the opening and closing of solenoid valves, adjusting the fuel injection quantity according to engine operating conditions. In vehicles that have been driven for extended periods, fuel injectors are prone to clogging due to impurities in the fuel, necessitating cleaning or replacement. Some vehicles use standardized injectors, requiring no additional operation after replacing the original injectors; the vehicle’s ECU will automatical...
